An Efficient Stereocontrolled Strategy in the Cyclopropanation Reactions of α,β-Unsaturated Ketones with Semistabilized Ylides: Highly Selective Synthesis of Two Geometrical Isomers of Vinyl-Substituted Cyclopropane Derivatives.
-Starting from telluronium ylides cis,trans-substituted cyclopropyl ketones of type (III) are formed mainly, whereas the corresponding arsonium ylides lead to trans,trans-substituted derivatives of type ( IV). -(TANG, Y.
